Should we believe that the terms Messiah or Anointed are really true, because it should only be 50% or maybe even just a Third of a Messiah.?

50% of "Messiah." is "Mess".

What, are you referring to the heresy of the Trinity?  Relax, the Trinity doesn't exist.  Not only does it contradict dozens of scriptures, it is inherently self-contradictory.  The only thing in the Bible that supports the Trinity unambiguously is the forged Johannine Comma.  Jesus Christ is Jehovah incarnate, the creation and begotten son of God (who is Elohim), at least according to the Bible.  He is a separate and distinct being from God and from the Holy Ghost.  Yes, he is the Christ, the Messiah, the chosen savior of mankind.

It would be nice if that question made sense.
